AKs against two big stacks

[ManicLombax]

First of all is my pf 3-bet reasonable here? c/f flop seems pretty weak with this board but maybe that's the way to go. Both opp's were pretty active and aggressive. Seems like I'm probably up against AK/AQ. Possibly QQ, I'd think AA/KK would have put me all in pf but maybe not. What do you think?

If you 3-bet to this size you can't really just give up when you whiff so I'd just shove the flop.

Seems ludicrous to say they were both active and aggressive and suggest their range is limited to AQ-AK, QQ.

Good points, thanks baudib. I didn't mean they could only have AQ+, QQ, but rather I couldn't think of many hands that would call a fairly big 3-bet that included a 7,8 or T.

Think I'd be better off just shoving preflop here? I was planning on folding if I whiffed as I'd still have 11k left, but then thought maybe they'd whiffed as well. Probably a better semi-bluff if only one of them calls though.

Ugly flop, but with 1/3 of our stack in already we have to shove. Lots of times the villains will have a hand like QJ, 66, etc and likely fold to our bet. Even if someone shows up with say JJ, we're not totally dead with 2 cards to come.
